hw/arm/armv7: Fix crash when introspecting the "iotkit" device

QEMU currently crashes when introspecting the "iotkit" device and
runnint "info qtree" afterwards, e.g. when running QEMU like this:

echo "{'execute':'qmp_capabilities'} {'execute':'device-list-properties'," \
 "'arguments':{'typename':'iotkit'}}" "{'execute': 'human-monitor-command', " \
 "'arguments': {'command-line': 'info qtree'}}" | \
 aarch64-softmmu/qemu-system-aarch64 -M none,accel=qtest -qmp stdio

Use the new functions object_initialize_child() and sysbus_init_child_obj()
to make sure that all objects get cleaned up correctly when the instances
are destroyed.
